ALARM CODES
7-Segment Display
The left hand window shows the cabinet wall temperature.
The right hand displays show the probe temperatures during a blast cycle, and are normally blank
during store. If a probe fails it will indicate
pf
(probe failure) during a blast.
Cab temp window also acts as a count up timer in probe blast.
If there is an alarm condition, the top probe display will show an alarm number
a0
to
a7
during store (
see table below
), but will still show the probe temperature during blast.

Note: for each probe only one audible alarm and alarm printout is allowed to be issued
each day. This is to prevent excessive paper use and noise nuisance in the event of an
intermittent probe failure. However, repeated probe failures are displayed on the probe
display window, (top window in the case of 3 probe panels)
